Unfortunately this library is no longer maintained by the creator. But.
I just released the 1.0.0 version of my own react-native library that includes AdMob modules.
My code is based on this lib, but i made some refactoring, bug fixes and adaptations for Androidx libs and new react-native framework(0.60.3).
My library is for Android Only, so it is not a solution for IOS :/
